  • Sealing system for super-plastic gas-pressure forming of aluminum sheets
    Patent number: 6997025
    Abstract: A super-plastic forming tool for forming aluminum sheets is provided that includes a seal bead that is configured to facilitate removal of the aluminum sheet from the seal bead after a super-plastic forming operation. Contraction of the aluminum sheet at a faster rate than the super-plastic forming tool facilitates removal of the aluminum sheet due to the specific geometry of the seal bead. The seal bead has a more shallowly sloped outer surface than its inner surface and may be provided in different configurations including flat, convex, concave shapes.
    Type: Grant
    Filed: March 6, 2003
    Date of Patent: February 14, 2006
    Assignee: Ford Motor Company
    Inventors: Peter A. Friedman, Warren Benjamin Copple, George Luckey, Jr.

  • Method of making sand cores
    Patent number: 5758708
    Abstract: A closed core box is provided with one or more inlets for receiving and passing gas fluidized resin-coated sand to fill the interior of such core box, and with one or more screened outlets for allowing egress of such gas. A closed cylindrical or angular sand-fluidizing chamber is provided for each of the inlets, the chamber having one end connectable to a pressurized gas supply and an opposite end communicating with an inlet. At least part of each chamber is filled with resin-coated sand and a non-porous piston is placed on the sand within each chamber, each piston providing an annular gap (i.e. about 1/16 of an inch) with the interior of such chamber to direct the gas supply along the periphery of the chamber interior.
